SEISMIC STRENGTHENING STRUCTURE USING COMPRESSION BRACE
PROBLEM TO BE SOLVED: To provide a seismic strengthening structure using a compression brace, the seismic strengthening structure not requiring on-site welding work, being easily constructed and enabling a connection part of the compression brace to a building skeleton to have a little tensile strength.SOLUTION: A structure for strengthening an existing building using a compression brace is provided. A joint part 12A for jointing a lower end of a core material of the brace to a connection part between a column and a beam of a building skeleton has a vertical-direction connection plate part 12a and a horizontal-direction connection plate part 12b which face the column 30 and the beam 40, respectively. Loose holes 10 are formed in the connection plate parts 12a, 12b, and anchors 11 penetrating the loose holes 10 are provided in the column 30 and the beam 40. A receiving washer 13 for adjusting a height of the brace by receiving the connection plate part 12b is provided in the anchor 11 of the beam 40. A plane shape of the receiving washer 13 has a clearance formation part through which uncured nonshrinkage mortar 14 can pass to the loose holes 10. The nonshrinkage mortar 14 is filled between the column 30, the beam 40 and the connection plate parts 12a, 12b, and into the loose holes 10.
【課題】 現場での溶接作業を要せず、施工が容易で、圧縮ブレースの建物躯体との接合部に若干の引張強度を持たせられる圧縮ブレースによる耐震補強構造を提供する。【解決手段】 既存建物を圧縮ブレースにより補強する構造である。ブレースの芯材の下端を建物躯体の柱と梁との接合部に接合する継手部１２Ａは、柱３０および梁４０にそれぞれ対面する垂直方向および水平方向の接合板部１２ａ，１２ｂを有する。これら接合板部１２ａ，１２ｂにルーズ孔１０を明け、柱３０および梁４０には各ルーズ孔１０に挿通されるアンカー１１を設ける。梁４０のアンカー１１に、接合板部１２ｂを受けてブレースの高さを調整する受け座金１３を設ける。受け座金１３の平面形状を、ルーズ孔１０に未硬化の無収縮モルタル１４が通過可能な隙間形成部を有する形状とする。柱３０，梁４０と各接合板部１２ａ，１２ｂとの間、および各ルーズ孔１０内に無収縮モルタル１４を充填する。【選択図】 図３
